Sorry to hear that. As flimsy as ours is attached, I am not surprised it hasn't happened to more of us. I don't know for sure where another can be bought or fixed, but I would start with your local FR dealer. You can also try Roberts. They seem to know there stuff even know some people on the forum have had Cust serv issues with them.

I am sure a google search would be able to get you to someone they may also be able to help. Good luck and please keep us posted. Thanks
